WINDOW.

SPECIFICATION forming part of Letters Iateni'.A No. 295,362, dated March18, 1884. I Application filed August l, 1823 (No modell.) i

States, residing at Newark, in the county of Essex and State of NewJersey, have invented certain nev.T and useful Improvements in W'inydow-Sashes; and we do hereby declare the following to be a i'ull, clear,and exact descrip tion oi' the invention, such as will enable othersskilled in the art to which it appertains to make and use the'sa1ne,'rei`erence being had to the accompanying drawings, and to lettersof reference marked thereon, which form a .part oi' this specification.l

. g thus avoiding the necessity of getting outside ofthe window and thedanger common thereto.

The invention is also intended to more eftectually prevent i the passageof air and moisture through the interstices of the frame of the windowsas ordinarily constructed,and, fn rther, to do away with all rattlingand shaking of the window-frames.

The invention consists in such construction, combination, andoperationot' parts as will be hereinafter more fully described, and embodied inthe claims.

Referring to the accompanying drawings, in

, which similar lettersof reference indicate like parts in each of thevarious iigures, Figure 1 is a front elevation oi' a Window-frame andsaslies having attached thereto our device, the righthand side of thelower sash being broken away, showing the relation of our improvement tothe sash. Fig. 2 is an enlarged side elevation, partly in section,detached from th sash. Fig. 3 is a plan View of the detached attachment,also enlarged; and Fig. v4 is a crosssection taken throughline x of Fig.1.

In carrying out our invention we employ a supplemental piece, a, of thelength ofthe Windowsash from top to bottom, and of suitable thickness-`having a recess therein to re" ceive the working parts of our device.The stile of thc'sash is aiso provided with a recess corresponding tothe recess in the supplemental piece, but of less depth. In addition tothe supplemental piece a, we 'employ a metallic piece, b, preferablycylindrical, one'end of which, c, may be reduced in diameter, having athread thereon, the part b being about the length ofthe depth oi' therecess in the supplemental piece a, the central portion of said recessbeing cut away to receive said part b.

d is a locking-bar, which is contained within and is about the length ofthe recess in the supplemental'piece, and passes through a slotoropening in the cylinder b," having the de-v pression d therein, theuse of which will be described hereinafter.

e is a spring, which bears against the bar 'd near the extremitiesthereof, as shown. Said spring also passes through the slot b,beingsecured therein by a pin7 j?, which passes through the cylinder b,spring c, and bar d, serving to hold the parts in place. The pin f maybe dispensed with, if desirable, the spring c being riveted to the partb instead.

g is a cap sunk within the stile of the sash, having a female threadcorresponding to the thread on c, and provided with screw-lugs orflanges g', to secure the same, said lugs being placed, preferably, somedistance from the outeredge of the cap at the bottom of the recess insaid stile, as shown in Fig. 1.

h is a small lever,` shaped substantially as shown in Figs. 3 and 4, andpivoted `.vithin a slot, bin the cylinder b, as indicated, one end ofsaid lever bearing against the locking bar d on the side opposite to thespring, and the other end projecting through the slot b, and alsothrough a corresponding slot in the supplemental piece a, as shown inFig. 4. Pivoted to the supplemental piece c is a thumb or finger piece,c', the short arm of which bears against the part of the lever h whichprojects through the slot in the piecel a, the longer arm of said part ibeing adapted to be operated by the thumb or finger.

j is a plate secured to the supplemental piece ci, having thereon thelug or projection k.

The cylindrical part b is provided with iianges Z l, for securing saidpart to the piece a., as indicated in Fig. 8. rIhe cord to which the IOOWeight is attached issecured to the suppleinentalpiecea, fas shown inFig. `1. v

The operation and'relation of our device to the window frame and sashesare substantially as follows: The supplemental piecesb are connectedwith thevwindow-sashes at the side by the, screw c, which turns withinthe cap g; said cap being secured within the stile of the sash, as abovedescribed. The said pieces a slide within the ways or grooves of thewindowframe, the j oints between the said supplementalv pieces and thewindow-sashes being placed outside of the stoplbead, so that` the sasheswill swing clear of the frame.-

The normal position of the locking-bar is shown in Figs. l and 2, where,bythe pressure of the spring e, it extends o-ver the'v joint between thesupplemental pieces a andthe sash, into the recess in said sash, thuscovering'that portion of the joint and excluding air Vand moisture, andalso by locking the sash prevents its turning and rattling. The depression d in the lockingbar allows said bar to extend into the recess inthe sashas will be evident by reference to Figs. l and 2.

The window may be unlocked by pressing the long armof the thumb-piece 11toward the outside ofthe frame. Thisfacts'upon the small lever h, which,in turn, presses the lockingbar d away from the sash and uncovers thejoint, thus permitting the sash to be rotated upon the screw-pivot c.

Fig. 4 shows the locking-bar thrown back by the pressure ofthe lever h,and theposition of the thumb-piece t', when the bar isthus thrown'backand held, is rshown under line x of Fig. 1. The lug 7c on the plate jholds the piece z' and prevents the bar d from springing back into therecess in the sash. The thu mbpiece may be disengaged from th'elug k,when desired, by a slight movement of the thumb,- as will be readilyunderstood.

It will be evident from the construction of our device that the screwson one side'of the .sash must be right screwsand those on the other sideleft screws, in order that the'sas-h may revolve. By this yarrangementlthe .screws not only act as pivots,but serve-to' tighten thezsash whenclosed. j

In order to more fully cover theVV joints between the sash andsupplemental pieces a, Where they are not covered by theLlock-in'g-ba'r,we recess the said piece a at af and a2, Fig. 3, and either attach tothesash or form `integral therewith projections a3, Fig. 1, which yi-t intosaid recesses, and thus break the joint and effectually prevent theentrance of air and moist-v ure.

Ourimprovement may be applied to any wi-ndowv by cuttingzaway a portionof thesash and substitutingtherei'or the supplemental piece with itsattendant parts d b c, Svc., without otherwise disturbing thewindowframe and sashes.

rlhe minor details of our invention may be varied without departing fromthe spirit thereof, as willvloe` readily understood.

Having thus described our invention, what we claim, and wishfto secureby Letters Patent, is-

l. The combination, with the sash or sashes of awindow., having recesses(as r) therein, and projections a3, of a supplemental piece (as a)having a recess'therein, and provided with recesses a and a2, adapted toreceive said projections a3, a locking-bar, d, and a spring, e, allsubstantially as and for the purposes set forth.

2. rlhe combination, with'the sash or sashes.V

of la'window, having a recess therein, and a cap (asg) provided with athread, of a supplemental piece having a recess therein, a cylindricalpiece, b, provided with a screw, ,0, and having a slot or opening, b',therein, a locking-bar, d, having a. depression, d', said locking-barmoving within said slot b in thepiece b, and a'spring. secured to'orwithinsaid piece b, all asset, forth.

3. In a window attachment, the combination of a'cylindrical piece (as b)having a slot, b, therein, `and provided with ascre'w, a lockingbarmoving within said slot, vaspring, and means for operating saidlocking-bar, all substantially as and for the purposes set forth.

4. In a'window attachment, the combination of a cylindrical piece (as b)having a slot, b', therein, and provided witha screw, a lock-ingbarmoving within saidr slot, a spring, (asia) a lever, h, pivoted orattached tothe cylindrical piece b, a thumb-piece, (as 1',) and a lug,k, all substantially as set forth.

5. In a window attach/ment adapted to be applied to the sashes of awindow, the combination of asuppl'emental piece (as a) having a recesstherein, a locking-bar, (as d,) a spring, (as 6,) a device (as b)providedl with a-screw, c, and adapted to hold said bar and spring inoperative relation, ya lever', h, pivoted to said device b,1athnmblpiece, and a cap, g, allV substantially as and for the purposesset forth.

. In testimony that We claimt-he foregoing we i 1o havey hereunto set'our hands this 21st day of July,1883; Y
